HEATENG APPARATUS.

Application filed January 27, 1923. Serial No. 615,233.

. To all 'wlw/m. t may concern.'

te it known that L Dnvm S. MURPHY, a citizen oi the United States ot America, and resident ot Fort lilayne, in the county Allen and State ot Indiana7 have invented certain new and useful Improvements in Heating Apparatus, ot' which the following is a specification.

'lhis invention relates to improvements in heating apparatus and the objects thereof are: tirst, to utilize the heat that ordinarily passes from a stove through the smoke pipe and wasted g` and second7 to provide means for the reduction in the amount oi smoke that ordinarily is caused by incomplete combustion of the fuel.

These objects are accomplished by the con- `lstruction illustrated in the accompanying drawings, in which liipj, l is a side elevation of an apparatus embodying the invention. portions being broken away and in section;

iP 2 is a plan view projected trom Fig. 1; and

Fig. 8 is a vertical section ot' a heat trap ot modified form.`

The characters appearing in the description refer to parts shown in the drawings and designated thereon by corresponding characters.

ri`heinvention comprises a stove 1 that is y located in a drum 2 which is of a size that aliords a space 3 between its linner walls and thel shell Af of the stove, the bottom of the drum being open. rihe stove has a smoke pipe that extends through the top ot :i closed box G and terminates'at a point near thebottom ot the box. lA second smoke pipe 4" extends through thetop of the box and terminates aiso at a point near the bottom ot the box.

Upon each pipe 5 and 7 is arranged an adjnstabie extension Flthat is provided with a rod 9 by means o` which the extension may he vertically adjusted.` The rod has a Ytoot 10 which limits the movement ot the extension by coming` intok contact with the bottom of the bor: `when the extension is moved downward7 and by coming into contact with the lower end ol the smoke pipe when the extension is moved upward. rllhe box 6 is located tended ifor connection with a chimney (not shown).

That portion ot the pipe 5 that extends `from the drum 2 to the other drum V11 is enclosed by a j a clret 13 ot a size that atords a space 141. between its inner wall and the pipe 5, andthe pipe is provided with a damper i5. The jacket 13 has openings 16 near its ends and a pipe 17 has connection at one/"end with the jaclret and at its other end with grate ,18. j That portion of the smoke pipe 7 that extends :trom the drum 1l to the chimney is enclosed by a jacket 19 that is 'of a size that affords a space 20 between its inner wall ano tno pipe7 the jacket being provided with a number et openings 21 and 22.

The drum 2 has a pipe connection y23 at its top with a het air pipe 24, and the drum 11 has also a pipe connection 25 at its top with said hot air pipe so that the heat from leading` Yfrom vthe drum 2 it is the intentionr that dditional connections maybe provided when needed tor conveying heat to various places Such an additional pipe 29 is shown in connection with the drum 1i at one end and with the pipe 24 at its other end. rlhere is also shown in the top ot the drum 1l a lid. Si) that may be removed for the admission oi heat :trom the drum directly into the room. in which the Ydrum is located. ln the side ci" the drinn 11 is a` door 31 located at a point higher than the box 6 so that articles be heated by ,being placed through the door opening intothe heat box and the space in the upper part of thedrum utilized as an oven. In the lower part .ofA

the stove at a. point beneath theyv Vsmoke from the stove passes through the smoke pipe 5 into the heat box 6 which becomes heated thereb and the smoke thus relieved ot a portion of its heat passes from the lower part of the box out through the 'smoke pipe 7 to the chimney. Also, the air in the space le: in the jacket 13 becomes heated by the radiation ot heat from the Vsmoke pipe 5; they heated air Jfrom the jacket being conveyed by the pipe 17 to a Vpoint beneath the grate in the stove' so that the air supplied to the fuel is initially heated by the hre that itsupplies.

The air that is heated in the jacket 19 .by the radiation ot heat Jirom the smoke pipe T may be conducted to points more or lessV remote by connecting pipes 22 with the openings 22 in the jacket.

l The air in the space 27 in the jacket 26 becomes heated by the radiation of heat from, the pipe 24 and is retained about the pipe 24 and its connection 23 so that the heat passing through the hot air pipe 24; conserved therein. Vhere the heat is to be conveyed toa distant point, the pipe 24, and jacket 26 thereoit are lengthened accordingly. l'n this manner the heat in the pipe 24; may be conducted a great distance.

The draft of smoke through the lower .part of the heat box 6 from the pipe 5V into the pipe 7 may be regulated by raising or loweing the extensions 8. and when adjustedto the desired positions are hold in place'by means ot coiresgondinf set-screws VY38 by which the rods 9 are secured.

L In the modified form the interior ot the box becomes heated by radiation from the smoke pipe andits branch, and also lby the `hot smoke thatjnialv enter the box through the open extensionrf. Inthis li'ormv lthe smoke pipe has connection asin Athe former ins'tv-f'iee'with the stove and the l. lnfcombination with a stove'7 a 'druml having an open bottom and enclosing the Vstove there ,being a space between the walls 7 i t L otthe drum and the ,Ashellol the stove; a
